Thermal microhabitats are often uncoupled from above-ground air temperatures. A study focused on small frogs and lizards from the Philippines demonstrates that the structural complexity of tropical forests hosts a diversity of microhabitats that can reduce the exposure of many cold-blooded animals to anthropogenic climate warming.

If you have ever entered a cave or an old church, you will be familiar with its coolness even in the dog days of summer. At much finer scales, from centimetres to millimetres, this ‘cooling effect’ occurs in complex ecosystems such as those embodied by tropical forests. The fact is that the life cycle of many plant and animal species depends on the network of microhabitats (e.g., small crevices, burrows, holes) interwoven by vegetation structures, such as the leaves and roots of an orchid epiphyte hanging from a tree branch or the umbrella of leaves and branches of a thick bush.

Much modern biogeographical research addressing the effects of climate change on biodiversity is based on macroclimatic data of temperature and precipitation. Such approaches mostly ignore that microhabitats can warm up or cool down in a fashion different from that of local or regional climates, and so determine how species, particularly ectotherms, thermoregulate (1). To illustrate this phenomenon, Brett Schefferset al. (2) measured the upper thermal limits (typically known as ‘critical thermal maxima’ or CTmax) of 15 species of frogs and lizards native to the tropical forest of Mount Banahaw, an active volcano on Luzon (The Philippines). The > 7000 islands of this archipelago harbour > 300 species of amphibians and reptiles (see video here), with > 100 occurring in Luzon (3).

As many of you are already aware, Franck Courchamp and I published a paper in Nature Ecology and Evolution on Monday that ranked high-profile ecology papers. I won’t go into any details about the list here, because you can read the paper and the associated blog posts themselves.

The publication caused a bit of a stir among ecologists, evidenced by the rather high and rising Altmetrics score for the paper (driven mainly by a Boaty McBoatface-load of tweets). I haven’t done any social-media analysis, but it appears that most of the tweets were positive, a few were negative, and a non-trivial proportion of them were highly critical of the obvious male-biased nature of the list (in terms of article authors).

On that last point, we couldn’t agree more.

Which is why we have a follow-up analysis specifically addressing this gender bias, but that’s currently in review in Nature Ecology and Evolution.

If you’re a regular reader of CB.com, you’ll be used to my year-end summaries of the influential conservation papers of that calendar year (e.g., 2016, 2015, 2014, 2013), as somewhat subjectively assessed by F1000 Prime experts. You might also recall that I wrote a post with the slightly provocative title Essential papers you’ve probably never read back in 2015 where I talked about papers that I believe at least my own students should read and appreciate by the time they’ve finished the thesis.

But this raised a much broader question — of all the thousands of papers out there that I should have read/be reading, is there a way to limit the scope and identify the really important ones with at least a hint of objectivity? And I’m certainly not referring to the essential methods papers that you have to read and understand in order to implement their recommended analysis into your own work — these are often specific to the paper you happen to be writing at the moment.

The reason this is important is that there is absolutely no way I can keep on top of my scientific reading, and not only because there are now over 1.5 million papers published across the sciences each year. If you have even the slightest interest in working across sub-disciplines or other disciplines, the challenge becomes more insurmountable. Finding the most pertinent and relevant papers to read, especially when introducing students or young researchers to the concepts, is turning into an increasingly nightmarish task. So, how do we sift through the mountain of articles out there?

We had a fantastic round of applicants for our previously advertised position in palaeo-ecological network modelling, and had offered the position to someone who had great potential.

Well, due to unforeseen circumstances (the person to whom we offered the position received another offer for a longer contract in her existing place of residence; such is life), we now have to re-advertise the position, and this one is open to both genders.
